So i want to add some 2x2 strips to my 2x4 studs to make them 2x6 which would give me space to fit in Roxul R23 which fits into a 5 1/2 inch stud (2x6). The issue im having is that my 2x4 are actually only 3 1/2 inch wide and the only 2x2 i can find are only 1 1/2 inch wide which gives me 5 inch studs. Am i able to compress the insulation 1/2 inch. Or should I do something else all together?

News alert....

A 2x4 is actually 1.5 x 3.5....been that way for a long time....2x6 is 1.5 x 5.5....

Maybe a bit more information...like where you live....what the existing wall is like....we are assuming that you have already pulled all of the drywall off...

Lacking any more info....if it was me....I would rip some 2x6's down the middle...or just sister 2x4's to the existing studs so that they stick out the depth you want.
